Satellite Data Reveal Magnetospause K-H Waves Impact Auroras
Analysis of multiple satellite data has revealed a striking connection between K-H waves on the magnetopause, surface waves in the hot zone near the plasmapause, and auroral undulations.

Charging Thunderclouds Affect Ionospheric Conductivity
As thunderstorm updrafts strengthen, electrification of clouds can heat the lower ionosphere, explaining prolonged disturbances to radio waves in the rarefied atmospheric layer.

Seeing Waves: GNSS Tracking of Waves in the Upper Atmosphere
Dense GNSS networks enable scientists to track large-scale waves traveling through the upper atmosphere, away from sources in the auroral zone and the day/night terminator.

Equatorial Ionospheric Scintillation During Daytime
Scintillation—flickers and distortions in radio waves passing through the ionosphere—can happen during daytime and at much lower dip latitudes than previously thought.
